6 Claims. (Cl. 126-99) i My invention relates to heating apparatus of the type usually employed to heat dwelling houses, and it has for a broad object to provide apparatus of this type which is of improved construction and arrangement of parts and which is simple in design and inexpensive to manufacture.

A further object is to provide a warm air furnace having an improved form of heating unit and an improved and simple means for supporting such unit within the outer furnacecasing.

The invention consists in the novel construction and combination of parts, to be more fully described hereinafter, and the novelty of which will be particularly pointed out and distinctly claimed.

In the accompanying drawings, to be taken as a part of this specification, I have fully and clearly illustrated a preferred embodiment of my invention, in which drawings- Fig. l is a vertical sectional view showing one preferred embodiment of my improved heating apparatus, the section being taken on the line l--I of Fig. 2;

Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. l; and

Fig. 3 is a perspective view illustrating my improved unitary heating means.

Referring now in detail to the construction illustrated, it is noted that I have shown my invention as embodied in an upright warm air furnace Il! wherein the air to be heated is drawn into the bottom thereof by a fan Il, which fan forces the air upwardly through the furnace and over the external heat-emitting surfaces of a heating means l2 and thence out through the top of the furnace to the space to be heated. It is to .be understood at the outside that my invention is not to be considered as being limited to this particular type of heating apparatus, for, in so far as the broader aspects of my invention are concerned, it might equally as well be embodied in other types of heating apparatus.

The furnace I comprises a rectangular casing `I3 formed by four vertical side panel walls I5, I6,

Il and IB, respectively, formed of sheet metal and extending for the full height of thefurnace and joined together at the four vertical corners to .Y

form a. rigid upright casing structure adapted to be supported by its bottom resting on any suitable support, such asl a floor, indicated by the line I9.

The lower part of the side panel wall i6 is pro-- ,foreign parueies from the entering air. n top wall 23, also of sheet metal, joins the upper ends ofthe walls I5, IB, Il and I8 and is provided with an youtlet opening 24 through which the heated air flows from the casing i3.

The casings divided horizontally by a wall 25 into a. lower air inlet chamber 26 and an upper heating chamber 2l. The fan Il is suitably motor driven and is arranged Within the lower chamber 2S. The fan has an axial air inlet 28 and a tangential air outlet 29 which discharges the air upwardly through an opening in the division wall 25 and into the heating chamber 2l.

Arranged within the heating chamber 2l of the casing is the heating means I2 which is formed as a one-piece structural unit (see Fig. 3). The heating means or unit I2 is here shown as comprising an upright frustro-conical shaped combustion chamber 30 formed of sheet metal and arranged with its smaller end at the top. The heating unit I2 also comprises anannular sheet metal radiator 3l encircling and spaced from the small upper part of the combustion chamber 30 and rigidly joined thereto by a tubular connecting duct 32 formed of sheet metal and suitably welded at its ends to the dening walls of the chamber 30 and radiator 3 I, respectively. In order to pro.- vide amore rigid connection between the combustion chamber and radiator, a vertical brace plate 33 is arranged therebetween and welded along its two vertical edges to the chamber 30 and radiator 3l, respectively. The heating unit I2 also comprises an oil burner 34, here shown as being of the vaporizing or pot type. The top of the burner is of substantially the same diameter as the bottom of the combustion chamber and is rigidly secured to and supported by the combustion chamber by means of hanger bolts 35 secured at their upper ends to brackets36 spot-welded to the chamber 3l!l and secured at their lower ends to angle pieces 3l extending beneath and supporting the bottom of the burner 34. Airis supplied to the burner 34 through a sheet metal utility duct 38 fixed at its inner end to the burner 34 and extending-laterally and outwardly through an opening in the side panel wall I5 of the casing.

As the burner' 34 is of a type well known to those skilled in the art, a detail description thereof and of its operation is unnecessary, it being sufficient to say that the llame produced by the burning oil projects upwardly through an opening 39 in the top of the burner and into the combustion chamber 30. .The hot combustion gases flow upwardly through the combustion 'chamber 30 and out of the chamber through the connecting duct 32 to the radiator 3|. A vertical bale wall 40 within the radiator 3| and adjacent the duct 32 causes the hot gases to flow clockwise (as viewed in Fig. 2) through the radiator to a smoke outlet duct connection 4| extending outwardly from the radiator 3| and through an opening in the upper part of the panel wall I8.

The heating unit I2 is also provided with a utility duct connection 43 which is also formed of sheet metal and extends outwardly from the lower part of the combustion chamber 38 and through an opening in the panel wall I6. The connection 43 serves as a means for observing the operation of the oil burner. Another utility connection is provided by a sheet metal duct 45 extending outwardly from the radiator 3| through an opening in the wall I5. The duct 45 is used as a means for gaining access to the radiator for cleaning the same.

As stated above, the heating means is formed as a one-piece structural unit. A supporting rod 50 extends across the top of the unit I2 and through alined openings in a pair of rigid supporting elements or hanger plates 6| and 52, respectively, which are located at diametrically opposite sides of the heating unit and are suitably welded to the outer dening walls of the radiator. The two ends 53 and 54 of the rod 50 provide rigid supporting elements for the unit I2 and extend outwardly from opposite sides of the radiator 3| to opposite corners of the casing I3. The two ends 53 and 54 extend through vertical slots 56 provided in bracket devices 51 and 58, respectively, the latter being suitably welded to the walls I1 and I8, respectively. As shown in Fig. 2, the rod 50 is threaded at its ends and is xed with respect to the hanger plates by means of clamping nuts 68 threaded on the rod and engaging the outer faces of hanger plates and 52, respectively. The end 53 is xed to the bracket device 51 by means of a pair of clamping nuts 62 and 63 threaded on the end 53 and engaging opposite sides of the part of the bracket 51 carrying the slot 56. Likewise, the end 54 is xed to the bracket device 58 by means of a pair of clamping nuts 64 and 65 threaded on the rod and engaging opposite sides of the part of the bracket 58 in which the vertical slot 56 is formed.

The rod 60 and brackets 51 and 58 provide a simple and effective means for suspending the heating unit I2 from thecasing I3. The slots 56 in the brackets 51 and 58 and the clamping nuts 62, 63, 64 and 65 provide a means for adjusting vertically either end of the rod with respect to the casing I3 so as to properly level or position the heating means within the casing I3. 'I'he utility connections 38, 4|, 43 and 45 are attached to thecasing walls by means of screws extending through the walls and through radial flanges 1| formed as a part of rings 12 which are spot-welded, respectively, to the several utility connections. The weight of the unit I2 is carried by the rod 50 and brackets 51 and 58, the connections 38, 4I, 43 and 45 with their rings 12 screwed, to the casing walls provide a means of steadving the unit and preventing sideways displacement thereof. It will be noted that the rod 50 substantially intersects the vertical axis of the unit I2 at a substantial distance above the center of mass thereof.

In addition to the advantages of simplicity and of low cost of the construction described and to the improved and inexpensive means for supporting the heating unit, a further advantage is that because the combustion chamber is frus- I tro-conical in shape, the diameter of the radlator may be kept small for a given heat capacity of furnace without restricting the required now spaces for the air to be heated which are between the radiator and the combustion chamber and between the radiator and outer casing, respeotively.
